Polymer composites are an important class of materials widely being used for many applications. But the main concern of non-degradability and adverse environmental impact of the polymer matrices and the synthetic reinforcements have given forth the need of environmental-friendly polymer matrices and reinforcements used in them. An attempt of such kind is to use the natural plant fibres as the reinforcements that have no harmful impact on the environment and also, they are cost effective. With growing interest in natural fibres in recent years, a lot of work is being done in various directions, which need to be gathered up for a specific interest. So, the present article is an attempt to review and discuss the research works that have evaluated the natural plant fibres as reinforcements in polymer composites. Natural fibre composites show variation of properties such as fibre’s source, type and structure. Interfacial adhesion between the fibre and the matrix is the most important factor when tensile properties of natural fibre composites are under consideration. The interfacial strength can be improved by some chemical modification of fibre surface, which changes the adhesion between fibre and matrix. These features of natural fibres as compared to synthetic fibres are motivating manufacturers and the end users to switch to natural fibre-based products.

“…79 A lot of research is being carried out on hybrid composites in which natural fibres were used along with synthetic fibres. 80- 84 Hybrid composite combines properties of the fibres used in hybridization. It is also possible to use polymer blend just like Vignesh et al used the mixture of synthetic and natural resin in their study.…”

“…From these studies, it is evident that due to the change in reinforcement there is noticeable variation in improvement of tensile strength of epoxy (volume fraction being same for both cases). Hybrid composites using piassava and e-glass fibres were fabricated and characterised for their mechanical properties to determine the effect of hybridisation of piassava fibre by comparing their mechanical properties [14].…”

At present, hybrid natural fibre-reinforced polymer composites are popularly used for their remarkable specific strength. Natural fibre polymer composites have been explored by the researchers for their sprawling use in engineering applications. To achieve better mechanical properties, it is needed to test hybrid natural fibre composites with all possible combinations of their compositions which require a lot of resources. Thus, the present work deals with the investigation of mechanical properties of hybrid abaca-epoxy composites. Experiments were carried out according to full factorial design with three input parameters namely weight per cent of abaca fibre, particle size of red mud and weight per cent of red mud. Subsequent to this, a fuzzy model is developed to predict the mechanical properties such as tensile, flexural and impact strength of hybrid abaca-epoxy composites based on the experimental results obtained by their mechanical characterisation. Membership functions were constructed such that the fuzzy model can precisely predict the mechanical properties of hybrid composites. Moreover, a set of test case experiments were conducted so as to validate the fuzzy model. It was inferred from these test case results that the developed model can be used to predict mechanical properties of hybrid composites with a maximum accuracy of 87%.

“…The hygroscopic swelling and absorption effect on the mechanical properties of biocomposites revealed that the direction of the fiber played a major role in the improved mechanical properties [14]. Surface modification of fibers resulted in improved mechanical properties [15]. The flexural strength and tensile properties improved with longer coir [16].…”

Synthetic fiber polymer laminates are becoming competitive material for engineering and structural applications. In this work, an attempt is made to synthesize a laminate with natural as well as synthetic fibers to get the advantage of cost-effective natural fibers. Coir is a natural fiber available in significant amount in south India. The present work aims at manufacturing a strong, cost effective, light and low impact on environment hybrid material. Both GFRP laminates and hybrid (GFRP + coconut Coir) laminates were fabricated by hand layup method and compression molding. Physical and mechanical properties of this laminates such as tensile strength, impact strength and density were evaluated. Microscopy images of this laminates were arrived at through scanning electron microscope. Even though the performance of hybrid (GFRP + coconut Coir) laminates is relatively lesser than GFRP laminates, these hybrid laminates may be adopted in the industries where cost is an important design factor.
